Ake - Is it in Obama's power to stop supplying arms to Israel? I'm not 100% sure how the American political system works, but I understand that there are so many checks and balances in your constitution that such a controversial move would be easily blocked. Even if he wanted to stop arms exports, how would he go about it? And do American arms go to Israel specifically in order to attack Gaza, or as part of a general policy to maintain the balance of power in the region?
